Iivalve zamasango oxinzelelo oluphezulu: ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle
Kuwo onke amashishini ukusuka kwi-oyile kunye negesi ukuya kwimveliso yamandla kunye neekhemikhali zepetroli, ukubaluleka kweevalvu zesango ezithembekileyo ezinoxinzelelo oluphezulu akunakubaxwa.Ezi zivalo zidlala indima ebalulekileyo ekulawuleni ukuhamba kwamanzi okanye iigesi kwiinkqubo zoxinzelelo oluphezulu, ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle.
Iivalve zesango loxinzelelo oluphezulu zenzelwe ukumelana neemeko zoxinzelelo olugqithisileyo kwimibhobho kunye nezinye izicelo.Yenzelwe ngokukodwa ukujongana noxinzelelo oluphezulu okanye iigesi ngaphandle kokunciphisa ukusebenza okanye ukhuseleko.Ezi valves ziqhele ukwenziwa ngezinto ezihlala zihleli, kubandakanywa intsimbi engatyiwayo okanye intsimbi ephosweyo, ukuze zibe namandla aphezulu kunye nokumelana nomhlwa.
Enye yeenzuzo eziphambili zeevalve zesango loxinzelelo oluphezulu kukukwazi kwabo ukubonelela ngesitywina esiqinileyo.Oku kufezwa ngokusetyenziswa kwendlela yesango efakwe ngaphakathi kumzimba wevalvu.Xa ivalve ikwindawo evaliweyo, isango livala isitulo sevalve, lithintele nakuphi na ukuvuza.Olu phawu lubaluleke kakhulu kwiinkqubo zoxinzelelo oluphezulu, apho nokuba ukuvuza okuncinci kunokubangela ubungozi obukhulu bokhuseleko kunye nokulahleka kwezoqoqosho.
Olunye uphawu olubalulekileyo lwe-valve yesango loxinzelelo oluphezulu kukukwazi ukusingatha uluhlu olubanzi lweengcinezelo zokusebenza.Ezi zivalo ziyilelwe ukuba zimelane noxinzelelo ukusuka kumakhulu ambalwa eeponti kwisikwere intshi nganye (psi) ukuya kumawaka aliqela eeponti nge-intshi nganye yesikwere (psi).Oku kuguquguquka kuvumela ukuba zisetyenziswe kwiintlobo ezahlukeneyo zezicelo apho iimeko zoxinzelelo oluphezulu zikhona.
Ukongeza kokukwazi ukujongana noxinzelelo oluphezulu, ezi zivalo zineempawu eziphantsi zoxinzelelo.Ukuhla koxinzelelo kukuncipha koxinzelelo olwenzeka xa ulwelo okanye igesi ihamba ngombhobho okanye ivalve.Iivalve zesango ezinoxinzelelo oluphezulu zenzelwe ukunciphisa ukuhla koxinzelelo, ukuqinisekisa ukuhamba kakuhle kunye nokunciphisa ukusetyenziswa kwamandla.Oku kubaluleke ngakumbi kumashishini abeka phambili ukusebenza kakuhle kwamandla.
Iivalve zesango loxinzelelo oluphezulu nazo zenzelwe ukuba kube lula ukuzigcina nokulungisa.Ezi zivalo zihlala ziyilwe ngeebhonethi eziboshiweyo ezibonelela ngokukhawuleza nangokulula ukufikelela kumalungu angaphakathi.Oku kwenza lula ukuhlolwa, ukugcinwa nokutshintshwa kwezinto, ukunciphisa ixesha lokuphumla elineendleko.
Ukhuseleko luyinkxalabo ephambili kumashishini abandakanya iinkqubo zoxinzelelo oluphezulu, kwaye iivalve zesango eziphakamileyo zidlala indima ebalulekileyo ekuqinisekiseni indawo ekhuselekileyo yokusebenza.Ezi valve zixhotyiswe ngeempawu zokhuseleko eziqinisekisiweyo ezifana ne-stem backseat kunye ne-stem packing ukuthintela ukusebenza kwevalvu ngengozi kunye nokunciphisa umngcipheko wokuvuza.
Ukongeza, iivalvu zesango ezinoxinzelelo oluphezulu zihlala ziyilelwe ukuhlangabezana nemigangatho engqongqo yoshishino kunye nemimiselo.Bangena kwiinkqubo zovavanyo olungqongqo ukuqinisekisa ukusebenza kwabo, ukuqina kunye nokhuseleko.Ukuthotyelwa kwale migangatho kuqinisekisa abasebenzisi bokugqibela ukuba iivalvu abazisebenzisayo ziyahlangabezana nowona mgangatho uphezulu kunye neemfuno zokhuseleko.
Isishwankathelo, iivalve zesango ezinoxinzelelo oluphezulu ziyinxalenye ebalulekileyo yamashishini abandakanya i-high-pressure fluids okanye iigesi.Ikhono layo lokumelana noxinzelelo olunzima, ukugcina isitywina esiqinileyo, ukunciphisa uxinzelelo lokunciphisa kwaye kulula ukuyigcina kwenza kube yinto ethembekileyo yokukhetha izicelo ezahlukeneyo.Ngokukhetha iivalve zesango ezikumgangatho ophezulu, amashishini anokuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwemisebenzi yawo.
